also does anyone have anny pictures of this done and if you do the cat delete do you also delete the squished pipe that is after the cat but before the muffler .

I'd be interested to know also. I would imagine if there is any BHP increase that the Secondary Cat delete would be more of a restriction compared to the muffler.
